The generic "cure for diabetes" in the headline seems extremely misleading when the article suggest this is only for "brittle diabetes" which makes up only 0.3%

The generic "cure for diabetes" in the headline seems extremely misleading when the article suggest this is only for "brittle diabetes" which makes up only 0.3% of people with Type 1 diabetes which makes up only 6% of people with diabetes. So this wouldn't be a "cure for diabetes", it is a cure for "0.018% of people with diabetes".
